but i am capable of proving my own existence inside time. If i was a fish dreaming this then I wouldn't be able to post on this forum. Time, as described by science, has no beginning and no end, so as if u r going 2 take the litteral deffinition of time it is impossible to have something outside that. And it is a pretty far-fetched idea that I would be a fish dreaming that I am me sitting in front of my computer. U can't say that I do not exist. I can thing, eat, walk, talk, and do other activities. Everything in this world exits for the smallest particles of the atom to the whole universe and time itself.
